How to convert 800 watts to amps

How to convert electric power of 800 watts (W) to electric current in amps (A).

You can calculate (but not convert) the amps from watts and volts:

Amps calculation with voltage of 12V DC

To calculate the current in amperes (amps) for a DC circuit, you can use the following formula:

I = P / V

Where:

I = current in amperes (amps)

P = power in watts

V = voltage in volts

In this formula, the current is equal to the power in watts divided by the voltage in volts.

For example, if you have a 12V DC circuit with a power consumption of 800 watts, the current flowing through the circuit would be:

I = 800W / 12V = 66.667A

It's important to note that this formula assumes that the resistance of the circuit is constant. In some cases, the resistance of the circuit may vary (for example, if the circuit includes a variable resistor), which could affect the actual current flowing through the circuit.

Amps calculation with voltage of 120V AC

To calculate the current in amperes (amps) for an AC circuit, you can use the following formula:

I = P / (V x PF)

Where:

  1. I = current in amperes (amps)
  2. P = power in watts
  3. V = voltage in volts
  4. PF = power factor

In the formula, the power factor (PF) represents the amount of the apparent power that is actually used to perform work in the circuit. In a purely resistive circuit (such as a heating element), the power factor is equal to 1, so the formula simplifies to:

I = P / V

For example, if you have a 120V AC circuit with a power consumption of 800 watts, the current flowing through the circuit would be:

I = 800W / 120V = 6.667A

If the circuit has an inductive load (such as an induction motor), the power factor may be less than 1, so the current would be slightly higher. For example, if the power factor of the circuit is 0.8, the current would be:

I = 800W / (120V x 0.8) = 8.333A

It's important to note that the power factor of a circuit can vary depending on the type of load and the operating conditions. In some cases, it may be necessary to measure the power factor directly using specialized equipment.

Amps calculation with voltage of 230V AC

To calculate the current in amperes (amps) for an AC circuit, you can use the following formula:

I = P / (V x PF)

Where:

  1. I = current in amperes (amps)
  2. P = power in watts
  3. V = voltage in volts
  4. PF = power factor

In the formula, the power factor (PF) represents the amount of the apparent power that is actually used to perform work in the circuit. In a purely resistive circuit (such as a heating element), the power factor is equal to 1, so the formula simplifies to:

I = P / V

For example, if you have a 230V AC circuit with a power consumption of 800 watts, the current flowing through the circuit would be:

I = 800W / 230V = 3.478A

If the circuit has an inductive load (such as an induction motor), the power factor may be less than 1, so the current would be slightly higher. For example, if the power factor of the circuit is 0.8, the current would be:

I = 800W / (230V x 0.8) = 4.348A

It's important to note that the power factor of a circuit can vary depending on the type of load and the operating conditions. In some cases, it may be necessary to measure the power factor directly using specialized equipment.
